A new program for getting desperately needed food into the hands of starving Palestinians in Gaza is only days old, but it’s already mired in chaos and tragedy. Dozens of Palestinians have been killed over the past few days while on their way to trying to obtain aid from the Gaza Humanitarian Foundation (GHF).

It was the second such shooting in three days near a food distribution center, which is part of a contentious new Israeli and American-backed initiative.

Israel’s military said it fired warning shots at Palestinians who strayed from a route. Dozens more were injured in the shooting in Rafah, health officials and the Red Cross said.
